Baptism is an outward symbol of the transformation that has already taken place inside of you.
Baptism is the public proclamation of our new life in Jesus. As we are submerged under the water, we identify with Jesus’ death to all that is evil and unjust in this world; as we are lifted up from the water, we identify with the new life we share in Jesus (Rom. 6:3-5). Death, and the power of sin, has no authority over us.
Although baptism is not a requirement of salvation, it would be wrong to say it is unimportant (cf. Matt. 28:19-20). We freely identify with Jesus as an sign of obedience to Jesus and solidarity with Christ. As a public act of faith, baptism also serves as a source of encouragement and a communal celebration of the unity shared in Christ, and the life we live together through faith, hope, and love.
